KANSAS CITY, Mo. -- Some observations from Monday’s Kansas City Chiefs practice session:

• Tight end Travis Kelce left practice early because of a right leg injury. Kelce initially tried jogging off the injury. But shortly afterward he walked off the practice field under his own power, accompanied by trainer Rick Burkholder. He didn’t return to the practice field.

• Chris Conley replaced the injured Albert Wilson in the starting lineup at one of the wide receiver positions. Wilson, who injured his shoulder in last week’s game against Tennessee, may eventually get his job back. But Conley could make the decision difficult by playing well as long as Wilson is out.

• Wide receiver De'Anthony Thomas, who has an injured calf, worked during the early portion of practice but left the field as the Chiefs began full-team drills. Thomas later returned to practice after he had removed his pads.

• Safety Ron Parker made the play of practice when he stole the ball from James O'Shaughnessy after the rookie tight end had caught a pass and turned to head upfield. Runner-up goes to tight end Demetrius Harris, who made a diving catch in the end zone of a pass from Alex Smith.

• Safety Eric Berry also had an interception when he caught a ball that had been deflected by tight end Richard Gordon.
